Title: Bootstrap-integrator
IPC: H03K4/24
Filed: 1964-05-22
Abstract: 1,058,215. Hybrid bootstrap circuits. W. H. JOENS & CO. G.m.b.H. May 22, 1964 [May 24, 1963], No. 21291/64. Headings H3P and H3T. [Also in Division G4] In a bootstrap integrator circuit (Fig. 1) an input voltage U e  is applied over terminals 10, 11, and resistor 13 (R) to capacitor 12 (C) whose voltage U a  is connected to the grid of a triode cathode follower whose cathode circuit comprises the emitter base circuit of transistor 17 in series in the resistor 18. The collector base circuit comprises power source 19 in series with variable resistor 20 also returned to input terminal 11. A positive feedback voltage U r  is developed across resistors 18 and 20 proportional to the voltage U 18  across resistor 18 and thus to capacitor voltage U a , and by adjustment of resistor 20 is made equal to U a  so that the current i flowing into capacitor 12 is given by In a modification (Fig. 2, not shown) the cathode resistor is connected, between the triode cathode and the transistor emitter, and the base of the latter is returned to ground. In a modification (Fig. 3, not shown) the input voltage U e  is applied over a resistor (R) and a variable resistor to respective sides of a capacitor (C) whose voltage U a  is applied to the grid of a cathode follower triode; a balancing cathode follower triode having its grid returned to the junction of the cathode loads, the capacitor and the variable resistance. A PNP transistor 44 is base connected to the cathode of the balancing triode emitter connected to the cathode of the integrating capacitor triode, and collector connected through a voltage source to the input side of the variable resistor; adjustable to produce a voltage drop U r =capacitance voltage U a ; the charging current In a modification (Fig. 4, not shown) positive and negative input voltages U e  are applied over a selector switch and resistor to a capacitor and the grid of a cathode follower triode; the grid of the balancing cathode follower triode being connected to the slider of a potentiometer across the input voltages. The collector of the transistor is connected to the cathode resistance and integrating capacitor return over series variable resistances whose junction is connected to the grid of the balancing triode; opposed diodes being connected from this point to the junction of the integrating capacitor and resistance. The series variable resistances are adjusted so that the voltage inputs U a , U r  to the cathode followers are equal, and the potentiometer is adjusted to compensate the error in U r  due to any standing unbalance in the triode cathode currents for U a =0. The diodes are normally non-conductive since U a =U r  but operate to limit positive or negative charging of the integrating capacitance.
